Did I spend money on an exterminator too soon?

[Paul S.]

Hi everyone. About 2 years ago, a tenant in a townhouse caught a few mice in the basement over a few weeks. The problem stopped, but he caught 2 more mice recently. I called an exterminator for a treatment. It will cost about $600.

I wonder if I have spent the money too soon.

I am not an expert in pest control.

What if the tenant left a door open or something, and a few rodents slipped in?

However, if there IS a nest in the house, I think it would be good to have it professionally treated soon.

What would my fellow landlords have done?

Cheers,

Paul
